摘　　要：针对传统水平位移监测难以发现潜在变形危害的问题,本文提出了一种基于水平位移向量的扭曲性分析方法。该方法以水平位移向量为工具,通过构建观测向量矩阵对水平位移观测数据进行深度挖掘,以发现其隐含变化规律。实验结果表明,本文所提方法不仅能发现水平位移变化的一致性,而且可以有效发现水平位移扭曲变形,丰富了水平位移数据分析研究内容,为变形警报提供了一种稳定可靠的技术方法,也为相关水平位移监测工程提供了一个崭新的技术视角。According to the fact that traditional horizontal displacement monitoring is difficult to detect potential deformation hazards,a distortion analysis method based on horizontal displacement vector is proposed. This method used horizontal displacement vector as a tool,and constructed observation vector matrix to mine the horizontal displacement observation data in depth,so as to discover its implicit changing information. The experimental results showed that the proposed method can not only discover the consistency of horizontal displacement changing,but also effectively discover the distortion of horizontal displacement,and enrich the research content of horizontal displacement data analysis,and provide a stable and reliable technical method for deformation alarm,and also provide a new technical perspective for related horizontal displacement monitoring projects.
